ABSTRACT:
A locking device for mounting a heat sink to a CPU mounted on a printed circuit board, includes a first locking member extending the heat sink and the circuit board and having a block for pressing the heat sink, an operating member pivotably connected to the first locking member, a second locking member extending the heat sink and the circuit board and pivotably connected to the operating member, and an actuating structure formed between the first and second locking members. The first and second locking members each includes a hook located below the circuit board. The operating member is pivotable about the first locking member to drive the second locking member to move upwardly and to cause the actuating structure to simultaneously drive the first and second locking members to move away from each other, whereby the hooks engage below the circuit board.
